The built-in download manager of Firefox 35 has a long list of missing features including such a basic like download and upload data rate throttling. There are a lot of download managers available as complementary add-ons which don't interact with the built-in download manager (They can't be used when a download link is clicked on and/or need to be started explicitly when previous downloads ought to be resumed - when the downloads allow it). Further problems include duplicate configuration and traffic loss (when a download is started in one manager and requires features which are only available in the other and needs to be restarted).

I am looking for a solution which is not based on a concept which immanently wastes my time (as described above), i.e. a download manager which integrates with the build-in manager or disables it efficiently (including settings synchronization). I checked:

  • Download Manager Tweak 1.0.8: doesn't integrate with the built-in download manager, at least not with All-in-one Sidebar 0.7.25 installed; throttle features not checked
  • Modern Download Manager 0.2.1: integrates well with the built-in download manager and All-in-one Sidebar 0.7.25, but doesn't have any visible or accessible features

and gave up because it became a trial and error search.

A solution in form of an extension would be nice, but is not a requirement (I just can't imagine another solution).

    Why does the download manager need to integrate with the built-in option? Why not use a completely separate manager, like DownThemAll!, for your downloads? If you provide a little more detail about your use case, it should be easier to brainstorm possible solutions.

FlashGot and pyload do the job. FlashGot allows selection of the backend which is used as download manager (supports a large set of download managers) and pyload has any imaginable feature - in case one is missing one can still figure out adding other download manager backends.

The fact that a download cannot be resumed with a download manager after being started with another is inevitable.
